These high-protein coffee overnight oats were one of my all-time favorite recipes in 2025, so I had to bring them back to kick off the new year.
They pack 30 grams of protein from greek yogurt and your favorite protein powder, and they’re filled with cozy coffee flavor that you can easily turn into chocolate-y mocha overnight oats!
Mix up these simple ingredients and keep the oats in the fridge for a quick, easy, nutrient-dense breakfast to fuel your day. Check out the full post for lots of ways to customize them, too!
Ingredients in these high protein coffee overnight oats
These easy coffee overnight oats are made with simple ingredients and are naturally sweetened with a little pure maple syrup. Plus, they pack 30g of protein! Here’s what you’ll need:
- Yogurt: I like to use plain greek yogurt to ensure that the oats are nice and filling.
- Milk: feel free to use any milk you’d like. I prefer unsweetened almond milk.
- Coffee: you can either use cooled coffee or cold brew to get that coffee flavor punch.
- Maple syrup: naturally sweeten the oats with a tiny bit of pure maple syrup.
- Vanilla: a little vanilla extract brings out the sweetness.
- Oats: can’t have overnight oats without rolled oats!
- Protein powder: add a scoop of your favorite protein powder to get an extra boost of protein. I like to use unflavored collagen peptides.
- Chia seeds: I like to add chia seeds for a lovely boost of fiber, omega-3s, and a little more protein. They expand in the oats to help thicken them, too!
Turn them into mocha mousse overnight oats
These flavor add-ins are optional but SO delicious. Add a couple teaspoons of cacao powder or unsweetened cocoa powder, plus a couple tablespoons of mini chocolate chips for a rich mocha flavor. Cacao powder also adds a boost of antioxidants.
Can I use steel cut oats?
Unfortunately, no, I cannot recommend using steel cut oats in overnight oats recipes because they will not absorb as much liquid as rolled oats, so the texture will not be creamy.
Make these coffee overnight oats your own
There are a few easy ways to make these overnight oats your own! Here’s what I can suggest:
- Go dairy-free: simply use your favorite dairy-free yogurt, and remember to use a dairy-free milk. If you’re adding chocolate chips, make sure to also use dairy-free/vegan chocolate chips.
- Pick your protein powder: as I mentioned, I like to use unflavored collagen peptides to add protein to these oats, but I think a chocolate protein powder would also be delicious for extra mocha flavor.
- For the nut butter lovers: add some healthy fats and another fun flavor combo by drizzling, mixing in, or layering a spoonful of your favorite nut butter!
- Add some fruit: I think sliced bananas would be delicious on top when you’re ready to eat!
Easy coffee overnight oats in 3 steps
- Mix all of the ingredients. In a large bowl whisk together all of the wet ingredients, then stir in the oats, protein powder, chia seeds, and cacao powder (if using). Mix in chocolate chips, too, if you’d like.
- Chill the oats. Cover your bowl and refrigerate for at least 4 hours or overnight. This is important so that the oats thicken up (no cooking required!)
- Divide & serve. Divide the mixture between two 12 ounce mason jars (or bowls), add your fav toppings, and enjoy!
Storing tips
These coffee overnight oats will stay good in the refrigerator in your mason jar for up to 5 days, which makes them portable and easy to enjoy on the go. Just be sure to give them a good stir and/or add another splash of milk as needed before enjoying.

Really yummy. I topped it with some yogurt, banana and a little quinoa chocolate granola:)
Sounds delicious!!
I may have commented on this recipe before but regardless, it deserves another comment! I absolutely LOVE this recipe. The overall texture and flavor is terrific. I always add cocoa powder to make it mocha and add strawberries as a topping. A great breakfast and so filling!
So happy you love this one! Strawberries sound delicious, too 🙂
I have been making Monique’s recipes since 2017, I even pre-ordered her cookbook as soon as I could and have gifted it to others. We exclusively cooked out of her cookbook for almost all of 2025! That being said, her website recipes are no different in quality or awesomeness! This recipe is a really great one! I bought collagen peptides a while back and have had a hard time finding ways to use them. This breakfast fills you up, and is also super tasty and high in protein! 🙂
Thanks so much for your note – so happy to hear that! One of my fav overnight oats recipes here, too 🙂
This recipe looks incredible! Can overnight oats be eaten warm in the morning (heated up in the microwave briefly)?
I prefer them cold, but yes, you can heat them up!
Have you ever tried using espresso powder instead of coffee? What modifications would you suggest?
I typically only use espresso powder in baking recipes! The coffee provides the liquid in here, so I wouldn’t suggest swapping it out.
I’ve eaten these oats every morning for a month (blended, because I like the texture better that way)! I didn’t like breakfast before these oats. They changed the game! Between them and Monique’s arroz con pollo verde, my health journey is made easy!! Thank you!!
The BEST way to wake up! I’m glad you love both recipes!
What could I sub for protein powder?
Feel free to omit it and add a bit more oats!
Yum!! These are so yummy and unique from any other overnight oat recipes ive tried, they legit taste like coffee ice cream, and i love how high protein it is too :))
Absolutely! My new fav, too!
Ok these are really good, and I’m not a huge overnight oats fan because I usually find them bland. These are not and i love the touch of caffeine from the coffee. I cut the calories by omitting the protein powder, reducing the chia seeds, and substituting stevia for honey. I also use unsweetened chocolate almond milk to enhance the chocolatey flavor with the cocoa powder. Topped with a banana and my breakfast goals are complete!
So glad you gave these ones a try! New fav 🙂
This is such a good unique recipe. I’ve been making this once a week for a delicious healthy breakfast treat. I use whole milk and a tablespoon of cacao powder to make it mocha.
Love it!!
I can’t wait to try this! Would you change any measurements of liquid if I used oat flour or use blended oats?
Hmm yes, I think the texture will be much different with oat flour so I’m not sure how much of the wet ingredients I would add!
These oats have the perfect subtle coffee flavor! I used chocolate protein powder & left out the cocoa powder. Next time I make I will use it a little less milk because I like my overnight oats a little less liquidy.
Absolutely! Glad you enjoyed 🙂
Absolutely delicious. The first bite tasted like coffee ice cream. Doesn’t even need the chocolate, in my opinion, but I will try it and add this to permanent breakfast rotation. I love that I can dump my unused coffee right in to use the next day!
So good!! Glad you enjoyed!
I loved these and had them for breakfast the last 2 days. Your recipes never disappoint! Thank you!
So happy to hear that!
